Good design really does make all the difference when it comes to energy conservation. This residential building in Lustenau, Austria, has no active, energy-intensive heating, ventilation, or cooling systems. Instead, baumschlager eberle architects opted for passive design features that allow users to regulate indoor temperatures and ventilation themselves.
The building relies on natural principles to provide optimal environmental conditions within its well-insulated stone envelope. The inner layer of this shell ensures high compressive strength, while the other layer guarantees efficient thermal insulation. Recessed windows reduce heat gains, while sensor-controlled vents fastened on the inside provide fresh air.
In cold winter weather, waste heat ensures a high energy input and the window vents only open if the volume of carbon dioxide in the room increases. During summer nights, the vents open to induce a draft for natural cooling.
